This article presents the real difficulties and topological challenges while deploying the sensor networks for cold chain. At the highest level of deployment of a network, not only do we have to decide about the routing, but also have to come up with realistic scenarios. Link Quality based routing algorithms are used most of the time. In this context, routing parameters work well in simulation or in favorable conditions, but have limitations when we deploy them in the real network, especially when we have asymmetric links between the sensors. One of the answers is to add a few nodes with a high transmission power level which can act as the clusterhead and indeed these nodes really stabilize the system
